Refer to Figure 60. In Figure 61, the progression of
the vector can be followed as above, but the steps
now are at 30º intervals rather than at 60º, as in the
six-step inverter. Another significant advantage is
a reduction in harmonics imposed on the
incoming line as well as torque harmonics to the
load. Figures 62 and 63 further illustrate the
differences between six and twelve-step inverter
actions. The fifth, seventh, seventeenth,
